The galvanically insulated interface is an associated intrinsic safety item of equipment that is installed in a safe zone or in zone 2 in an IP 54 housing, thanks to the Ex nA protection mode. Its mission is to limit the level of energy that may appear in an electric circuit routed through a potentially explosive area, whatever the connection established upstream. In addition to its energy-limiting function, its facilitates the use of signals in safe areas (e.g., relays), converts signals (e.g., 4/20 mA to 0-10V) or duplicates signals. Other functions are also available, such as the threshold relay or powering intrinsic safety. Intrinsic safe relay Input : 1 x switch or proximity sensor Output: 1 x SPDT Option: without, clamp terminals Power supply: 24/48 Vdc DIN rail mounting housing ATEX / IECEx informations: EC type examination certificate LCIE 02 ATEX 6104X IECEx LCI09.0013X certificate [Ex ia] IIC (-20 °C < Ta < 60 °C) Group II (surface) - category (1) G/D Installation in safe zone Barrier for equipment installed in zone 0,1,2 et 20,21,22 See leaflet for a safe use

BZG788PLUS, GEORGIN

Zener barriers contribute to the intrinsic safety [Ex i] and are installed in safe areas. Their mission is to limit the level of energy that may appear in an electric circuit routed through a potentially explosive area, whatever the connection established upstream of the barrier. A barrier is made up of: - resistors that limit the current - Zener diodes that limit the voltage - fuses that protect the components When a fault voltage is applied across the input terminals of the barrier, the voltage that may appear in the explosive zone is limited by a Zener diode, which is in turn protected by a fuse. The current is limited to an acceptable value by the resistor. They can be installed in zone 2, thanks to the Ex nA certification in an IP 54 housing.

Z728.H, Pepperl + Fuchs

P&F Single Channel Zener Diode Barriers Zener barriers provide cost saving Ex-protection for various applications in process automation systems. The amount of energy transferred to the hazardous location is limited to a safe level incapable of igniting the explosive atmosphere. Typical application - transmitters, transducers, solenoid valves and relays Isolation Barriers Pepperl+Fuchs shunt zener diode barriers are for use as safety interfaces between intrinsically safe and non-intrinsically safe circuits. They are manufactured from Makrolon® and designed to conduct electrical signals - in either direction - between safe and hazardous areas and to limit the amount of energy which can be transferred from a safe to a hazardous area in the event of fault conditions occurring in the safe area. All systems shown are licensed for [EEx ia] IIC Class 1, Div1, Groups A-G
